Chapter 82 Mathematics is to cultivate interest

Nima! !
Just let someone solve the problem through dictation?Don’t play like this, math teacher, are you playing such a high-end game now?
Even if you ask us to mentally calculate two-digit addition, subtraction, multiplication, and division, we may not be able to answer this question in the first time...

will play.

Have you already started playing this trick in high school mathematics?
Zheng Yihang smiled slightly. He didn't intend to say anything about the contents of the books in the first class. The fact that these students were admitted to No. [-] Middle School in the city itself shows that their IQs are not low, and they will be able to understand the contents of the books sooner or later. Now Just to raise their interest.

Mathematics, if you are not interested in it, then what is the difference between the math class and chewing wax?
The real mathematics class should be immersed in it, and the joy of mathematics is...

Five seconds later, Zheng Yihang said, "Now please raise your hands if you know the answer."

In such a hurry?so hasty?

"Is there no one? No one can answer this question..."

"too difficult."

"I won't... this question is too difficult..."

brush!brush!brush!
But the next moment, the three raised their hands again.

Fang Chao was shocked, someone raised his hand two seconds faster than him...

City No. [-] Middle School is indeed the land of Crouching Tiger, Hidden Dragon. With the level of the CMO mathematics in his province, it is only the third place.

"What's your name, the guy wearing glasses at the sixth table in the third row?"

"Yang Ning."

Yang Ning spoke. He was also wearing a pair of glasses. According to the prescription, he was about 1.7 degrees. He was slightly obese. He was 140 meters tall and weighed about [-] kilograms.

Students these days don't pay much attention to exercise, even ordinary elementary school students weigh a lot.

"Yang Ning? Come on, tell me your answer."

"2012."

When Yang Ning answered the year 2012, Fang Chao and another classmate beat their chests and stamped their feet. They were a few seconds late and forced to be pretended by others.

Zheng Yihang smiled and said, "Yes, very good, the answer is correct, Yang Ning, please sit down first."

Yang Ning took his seat.

At this moment, the atmosphere in the class is a little different.

Who would have thought that in this class, there are so many crouching tigers, hidden dragons like dogs.

So that in the future, when people from other classes see math students, all the math geniuses in class [-] are absolutely to die for. There is also a dog king in class seven, who is simply the best.

But soon, Zheng Yihang said with a smile, "After playing two questions, then we will not be so serious. I will present a puzzle, and you will answer it?"

"No, Teacher Zheng, are you still here?"

"Mr. Zheng, if you come up with another question, we will really doubt our IQ."

"We all entered the city's No. [-] Middle School with excellent results in the senior high school entrance examination, but this is the first day of school, and I wonder if I entered the wrong class... After that, I will be afraid of mathematics. Teacher Zheng."

"Yes, Mr. Zheng, don't challenge our IQ."

Zheng Yihang smiled and said, "It was indeed a test of your basic skills and reaction ability just now, but this time it is really a very simple puzzle, which middle school students can understand."

"Is it?"

"Then Mr. Zheng, you can come up with a question."

"Okay, anyway, we have been humiliated once, and we don't mind being humiliated again."

Zheng Yihang walked back and forth among his classmates, and then he began to say, "You are all outstanding students carefully selected from various middle schools to enter the No. [-] Middle School in the city, and I should be considered a good teacher, but You seem to have a problem with me."

"Mr. Zheng, we have no objection to you."

"Mr. Zheng, don't talk nonsense, we all respect our teachers... You suddenly said that we have a problem with you, isn't that a lie."

"Shh."

Zheng Yihang made a silent movement.

After all, Fu Lingyan used to be the class monitor, so she said at this time, "Everyone be quiet, Mr. Zheng is caught in a situation, he is giving us a question."

"Ah, so it is."

"understood."

At this time, Zheng Yihang continued, "Because you have opinions on me, I, a new teacher who has just graduated for a few years, is a little shivering, afraid that you will make some small movements when I am in class, disobedient, and even disrespect my math. I don't care about the class, as your math teacher, I can't let this kind of thing happen. In order to maintain the friendship between me and you, I opened a big box at KTV and invited all the students to come. Sing loudly, but the premise is that every student who goes must wear a hat, and the color of the hat must be divided into black and white. Of course, in this party, both black and white hats must be available. "

Zheng Yihang's short words obviously brought the students into the situation he set up. For a while, everyone seemed to have come to KTV. This is a feast of hats, which is very interesting. They are even looking forward to this A party to liven things up.

And some students have captured some important information points from this scenario.

Mr. Zheng is a very amazing person. Although he is not very old, his way of playing tricks is somewhat unexpected. Fang Chao likes such surprises.

Old and interesting.

I originally thought that young teachers are not as good as old teachers, but old teachers are superior in qualifications, and new teachers are superior in that they have no constraints and have a new set of teaching methods.

"I will prepare another twenty black and white hats myself, then collect all your hats, turn off the lights, and each of you will choose a hat to wear on your head."

"So, our hat-trick began."

"Attention, after each of you chooses a hat, you can see the color of the hat on other people's heads, but you cannot see the color of the hat on your own head."

"So now, I'll have people turn off the lights, and if anyone thinks they're wearing a black hat, they'll slap themselves in the face, and the first time, there's no sound at all, so I turn on the lights for everyone to see again, and then I turn off the lights, This time, there is still no sound of slapping. What’s going on? I’ve obviously asked people to prepare black hats, and some of you do wear black hats. I don’t believe in evil anymore. Turn off the lights for the third time. , hehe, someone finally slapped me, bang bang bang, I didn't expect that there are people who are really abused, and they like to slap themselves..."

The students below were all giggling.

Teacher Zheng, you are too funny, right?
Are you really teaching mathematics and not cross talk?How can it be so cute?

But the next moment, Zheng Yihang asked, "Now, the question is, how many of our classmates are wearing black hats?"
